PreSonus ADL 700 High Voltage Tube Channel Strip

PreSonus ADL 700 High Voltage Tube Channel Strip

Beyond superb sound quality, the ADL 700s preamp is special because of its ease of use and flexibilityThe full-featured FET compressor in the ADL 700 was custom-designed to work with the ADL tube preamp and the new ADL 700 EQThe ADL 700s 4-band semi-parametric EQ was designed to match the preamp and compressor. It combines isolated filters and optimized, per-band Q to provide subtle signal-shaping without harsh artifactsWe’ve given the ADL 700 all the features you expect in a high-end professional channel strip, with flexible features that let you work the way you want to
